RADIATOR FOR MOTOR VEHICLES.

Application filed July 16, 1921. Serial No. 485,188.

To all whom t may concern.'

Be it known that I, ToMMAso GUARTNO, a citizen of Italy, and a Subject of` the King of Italy, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Radiators for Motor Vehicles, of which the following is a specification/ This invention relates to improvements in radiators for motor vehicles, and combe known as a sectional radiator.

The primary object of this invention is to provide a radiator for motor vehicles 4such that should one or more sections become injured so as to cease functioning, said injured sections may easily be removed and replaced by new sections without danger of injuring the remaining sections of the radiator. v

A further vobject of this invention is to provide a radiator for motor vehicles which is exceptionally simple in construction, eX-

tremely durable in operationand easy andinexpensive to manufacture.

Other objects and. advantages of this invention will be apparent to those skilled in the art to which it appertains when following description and the accompanying drawings; being understood however, that various changes in the form and proportions of the device may be made the appended claims without departing from the spirit of the invention.

In` the drawings forming .a part` of this specification in which similar characters of reference denote similar parts 1n the several views- Figure 1 is a vertical view of a portion radiator constructed in accordance with the present invention,

F Fig. 2 is a view taken on the line 2 2,

Fig. 3 is a perspective view of oneof the Ifins forming a part of the invention, and

Fig. 4 is a view, partly in section, of a modification o-f the device. Referring now, more particularly to the drawings, the numeral 1 denotes Water tubes forming part of the completed radiator lwhich are secured in any suitable manner into the usualheaders (not shown).

Figure 3 discloses a perspective view of the radiating plates or fins, a plurality of within the scope ofy yand consequently of tubes in each series,

which are removably secured to each water tube in a superposed manner. Each En comprises a plate 2, centrally perforated at 3, surrounding which perforation is a wall of bur 4. Two opposite edges of plate 2 are formed with angular fianges composed of portions 5 and 6; the portion 6 being arranged at substantially right angles to plate 2, and the portion 5 being substantially parallel to the plane of plate 2.

The ns are superposed, one upon another on the water tubes 1 through the medium of the perforations 3 in each iin, and, as can be clearly seen in Fig. 1, mutually support each other; the edges 7 of each iin resting upon, and being supported by, the edge 8 of flange 5 of the iin immediately below. As will be seen, the fins on each water tube are really nested one within the other. The bur 4 of each n serves to support the superposed iin, the plate 2 of said superposed iin, resting upon said bur.

In the assembling of the radiator, the fins on one tube are preferably arranged in staggered relation with respect toA those of the adjacent tube. Several means of accomplishing this may be resorted to, but it has been found perfectly practical to employ a spacing ring 9 at the bottom of alternate tubes. At the top of the tubes employing this spacing ring, a fin having a bur 10, greater in height than bur 4 is preferably employed, but, if desired, another spacing ring 9 may be used.

For holding the several parts of the radiator in fixed position, retaining elements 11 are provided which are perforated to receive the ends of water tubes 1. These re taining elements 11 may be soldered to the water tubes if desired, to ensure additional rigidity of the entire radiator.

The design ofradiator illustrated in Fig. 1 discloses a single series of water tubes, a Single series of ns. It is perfectly practical to provide a plurality tratedw in Fig. 4, wherein the water tubes are arranged in sets of -threes. The iins, therefore, will be consequently larger and each providedI with lthree perforations and three burs 12. The function of the fins and same being illusr the mounting thereof, willbe identical with thosel disclosed in Fig. 1, so no further description thereof will be-necessary.

Having thus described my invention,

what'I claim as new and desire to secure by Letters Patent of the United States,

1. A radiator comprising a plurality of water tubes, a plurality of fins secured toA each of said water tubes, each of said fins being provided with angular flanges and a bur for supporting a superposed n, means on alternate water tubes for positioning the fins of one water tube in staggered relation with respect to the fins on the adjacent tube, and retaining elements secured to said water tubes.

2. A radiator comprising a plurality of water tubes, a plurality of fins on each of said water tubes, means on said fins for supporting the same in superposed relation, means on said water tubes for retaining the ns thereof in staggered relation with respect to the finsA of the adjacent Water tube, and retaining elements for said fins secured to said water tubes.

3. A radiator comprising a plurality of water tubes and a plurality of ins removably secured to said water tubes, said ns having upwardly and outwardly extending flanges whereby said ins are supported in nested superposed position.

In testimony whereof, I hereby aiiix my signature.
